requires the following equipment:
• Optical fibres
• Opto/electrical converter for the PC
• PC
SPA cannot be accessed via PCM600.
When communicating between the local HMI and a PC, the only hardware required
is a front-connection cable.
SPA can be accessed via LHMI front only when using the Field
Service Tool Access (FSTACCS).
